Place it at the peak of the visual gag, after the setup has built up, then follow it with a vine boom for a heavier payoff or a metal pipe clang for a second clumsy hit, keeping it as the first hit and the other effect as the follow-through.

This is a brief cartoon elephant trumpet, lasting about two seconds, with a loud, exaggerated blast that sounds deliberately silly rather than like a real animal. It feels instantly goofy and over-the-top, turning a clumsy reveal or oversized reaction into absurd, kid-friendly chaos. Its playful, cartoonish tone makes the joke land at once, without any setup.
